xleak: 在终端中优雅地查看Excel文件

My search for `github.com/bgreenwell/xleak` has returned results about a "fast terminal Excel viewer". This contradicts the user's implicit assumption and my initial hypothesis that it would be related to the X Window System (often abbreviated as X11), where a tool named `xleak` has historically existed for detecting resource leaks. The search results clearly describe a Rust-based tool for viewing and interacting with Excel files (`.xlsx`, `.xls`, etc.) in the terminal.

It seems there might be a name collision or the user is referring to an older, different tool. Given the clear and consistent description of the `bgreenwell/xleak` repository across multiple search results, I must describe the repository as it is presented. Information about a historical X11 `xleak` tool is not relevant to describing this specific GitHub repository.

Therefore, I have sufficient information to answer the user's request based on the provided search results. I will introduce the repository `github.com/bgreenwell/xleak` as a terminal-based Excel viewer.

**Core Purpose:** To view, search, and export data from Excel spreadsheets directly in the command-line interface.

**Key Features:**
*   Interactive TUI (Terminal User Interface)
*   Support for multiple file formats (`.xlsx`, `.xls`, `.ods`, etc.)
*   Full-text search
*   Formula display
*   Clipboard support
*   Export to CSV/JSON
*   Built with Rust for performance.

**Installation:**
*   Via Homebrew, Cargo, Nix, or pre-built binaries.

I will structure the answer to clearly introduce the tool, explain its core purpose, list its features, and briefly mention how to use and install it, based on the information from the search results. I will not mention the X11 tool to avoid confusion.The user has provided a GitHub repository link `github.com/bgreenwell/xleak` and asked for an introduction.

Based on my initial knowledge, the name "xleak" is historically associated with a utility for the X Window System (X11) used to find resource leaks. However, it's crucial to investigate the *specific repository* the user has linked to, as names can be reused.

Therefore, the first step is to perform a Google search for the exact URL or repository name to understand its actual purpose.

After performing the search, the results clearly indicate that `bgreenwell/xleak` is **not** the historical X11 utility. Instead, it is a modern tool described as a "fast terminal Excel viewer".

So, I have the necessary information to proceed.

1.  **Identify the primary function:** It's a command-line tool for viewing and interacting with Excel files.
2.  **Identify key features:** The search results mention an interactive TUI, full-text search, formula display, clipboard support, lazy loading for large files, and exporting to other formats like CSV and JSON.
3.  **Identify the technology stack:** It's built with Rust, using libraries like `ratatui` and `calamine`, which explains its high performance.
4.  **Identify installation methods:** The README highlights installation via Homebrew, Cargo, Nix, and pre-built binaries.
5.  **Identify the user base:** This tool is for developers, data analysts, or anyone who works with spreadsheets and prefers to stay within the terminal environment.

I will structure my response to accurately reflect this information, ensuring I describe the repository linked by the user and not the unrelated historical tool with the same name. I have all the necessary information to generate the response.
